United States Patent Oflice I 3,251,529 Patented May 17, 1966 3,251,529 CARDBOARD CONTAINER WITH ORNAMENTAL EDGE Lewis Douglas Young, Providence, R.I., assignor to Douglas Young, Inc., a corporation of Rhode Island- Filed June 28, 1965, Ser. No. 467,304 3 Claims. (Cl. 2298) This invention relates to a cardboard container, often in the form of a box, which has a covering material over plain cardboard.

One of the objects of this invention is to present a more attractive edge on a container of this character.

Another object of the invention is to provide such ornamental edge without increasing the operations which are usual in providing such a container.

More specifically, the invention consists in providing a plunger or die which will have the reverse of the contour desired on the edge of the container formed in the die so as to impress the edge of the container as the covering on the container is placed in position.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

FIG. 1 is a perspective view of a container provided with an ornamental edge;

FIG. 2 is a sectional view, somewhat diagrammatic, illustrating the plunger in raised position after being used to position a covering on a container;

FIG. 3 is a bottom plan view on a larger scale of the plunger shown in FIG. 2; and

FIG. 4 is a perspective view of a fragmental sectional portion of a wall of the container on an enlarged scale.

In proceeding with this invention, a covering material is placed over a cardboard container in the usual manner, but as the inner portions of the covering material are forced into position along the inner surface of the walls of the container, the die which forces these into position is provided with shoulders which'will engage the edge of the walls of the container so as to contour the same into some shape which will present an ornamental etfect.

With reference to the drawings, 10 designates generally a container having opposite side walls 11 and 12 and opposite end walls 13 and 14. These walls are joined by either a top or bottom wall 15 depending upon whether this section of the container which is illustrated in FIG. 1 is the body or cover of the assembly. A covering material is placed upon the container by stretching the sheet material 16 along the wall 15 and upwardly along the sides and end walls thereof as at 17, 18, 19 and 20 which'is of a length to extend above the walls along which it is vertically disposed and then this covering extends inwardly over the edges of the walls as at 21 and then downwardly as at 22 and 23 and 24 and 25. A suitable adhesive is used to secure the covering in place.

The positioning of this covering on the container is done mechanically in a machine in which the container is set into a recess in the block 31 which positions the covering from the bottom along the outer surface of the sides and ends and then the covering is forced inwardly and is finally positioned along the inner surface of the side and end walls by a plunger designated generally 31 and having a portion 32 which will be apever, indentations are provided in the edges 21 of the covered side and end walls by reason of shoulders 33, extending outwardly along the four sides of the portions 32 of the plunger 31 and providing on these shoulders ribs 34 or some contoured or convoluted shape which will indent the edges 21 as at 35 (see FIG. 4) while at the same time the contour shoulders provide convex portions 36' between the recess 35 so as to provide an ornamental appearance on the edge of the container. These concavities 35 may extend at an angle to the longitudinal extent of the wall as shown in FIG. 3 which also leads to the harmonious and ornamental eifect of the edge. Two such sections as shown in FIG. 1 may be provided, one to telescope into the other with each having these ornamental edges as thus formed.

In order to cause the indentations in the edges to maintain their. shape, the covering must be of some sort of material that will maintain its shape, and this material may be a metal foil or it may be some paper containing some sort of heat setting filler such as per-oxylin to form this ornamental appearance. In this case an electrical coil 37 may be placed in the plunger 31 to be suitably heated so that the shouldered portions will be of a suflicient temperature to heat set a paper of this character. The heating will be in proportion to the length of time that the die or plunger engages the edge walls of the container and where the engagement is in the form of a strike, a higher temperature in order to convey the heat desired may be had. In other instances where the plunger is in engagement with the edge a longer length of time, a lower amount of heat will be utilized.
